Description
Choose CXA1800.1 when the subwoofer system genuinely needs the largest CX monoblock—up to 1,800 watts RMS at 2 or 1 ohm. It is for high-output bass systems where the enclosure, subwoofers and electrical system are built around that power class. Move down to CXA1200.1, 800.1 or 400.1 when the sub stage cannot use the extra output; buying the biggest amp does not fix a mismatched woofer or enclosure.
